SHEATHlNG-PLATE.

SPECIFICATION forming' part of Letters Patent No. 787,207, dated April 1l, 1905.

Applicatie tiled October Z7, 1904. Serial N0. 230,179.

'5e it known that l. lfllws loi-rinXsoN. aciti- Xen of the L'nitetl tStates of America. antl a resitlent of `Yew York city. horough of Brooklyn. county of liings. au l State of NewYork. have invented certain new antl useful linprovements in Sheathing-Plates. of which the following is a specilication. reference heilig' hail to the aceonumuyiug ilrawings. forming a part thereof.

.\ly invention relates to improvements 1n shealhing-plates such as are applicahle for covering ceilings. walls.r antl the like.

.\ly invention consists in interlocking sheathing-plates' constituting sectional sheathing',

which may he huilt upto constitute a surfaceture complete in itself.

hine the various tlesirahle qualities in a single inilivitlual plate. the ashestos lining heing selfeontainetl therein: anil to this euml my invention eonsists in certain iletails of construction, as will hereinafter more fully appear.

l will now prot-eetl to tlescrihe a sheathingplate einhorlying my invention ainl will then point ont the novel features in the claims.

ln the ilrawings. liigure l is a face view of a set-tion of sheathing comprising a nuniher of individual sheathing-plates emhotlying my ini vention. showing the saine iuterlocketl antl in position. the view thereof heing taken from the ins-ille that is. from the siile against the surface which they are intentlell to cover.

Fig. 'l is a similar view of one of the sheathi ing-plates. on an enlargetl scale. Fig. il is a sei-tional view of the saine, taken upon the line l), I of Fig. '2. showing a portion of another plate interlocketl therewith. Fig. it is an outsiile face view of a sheathing-plate enihotlying my invention. showing the surface of themetallic portion thereof stanipetl up for receiving plaster, stucco. or the like. Fig. 5 is a transverse `sectional view of same. taken upon the line 5 5 of Fig. t.

The sheathing-plate as a whole comprises a metallic hacking l antl an ashestos lining 2. The metallic hacking is preferahly stamped up from sheet metal. the etlges or flanges heing otl'set from the main or holly portion.

Referring particularly to Figs. 2 and 3. it will he .seen that the plate has two narrow 50 llanges I' anil t and two wille llanges 5 ainl t3. 'l`he narrow [langes I), anil t are merely otl'set portions from the main hotly portion T, while the flanges 5 and t3 overhang the hotly portion T, as at 8, therehy formingpockets to receive the etlges of the ashestos sheet '2. ln this way the ashestos sheet of each plate is selfcontainetl therein hy the saitl overhanging portions 8. so that the sheathing-plate as a whole may he soltl as an article of manufac- Ylhe interlocking' of thc` platesonc with the other causes the flanges 5 and to overlie the ashestos sheets of the contiguous plates, wherehy all the edges of the ashestos sheets will he entirely protected when the plates are in position. as clearly shown in Fig. 1. i preferahly punch recesses J in the flanges 5 antl (3 of the plates. tlu'ough which nailsl may he reailily ilriven to secure the plates in position. antl it will he seen that SO when the plates are thus in position the nailheatls of one plate will hehithlen hy theoverlapping of the plates adjacent thereto.

lt will he notieetl that the hlank for each plate is so foriuetl that the llangesol' the coln- S5 pletetl plate coutume for the entire length antl hreatlth thereof. the outer houinlary of the saitl plate heilig' suhstantially rectangular. 'lhis insures complete overlapping, so as to make the sheathing' when complete practicaltv 90 continuous. antl it will he untlerstootl that. if tlesire-tl, a little sohler may he employetl along' the etlges. so that the sheathing may when linally construetetl he actually a continuous integral structure.

The outer face of the sheathing-platel may he smooth, if tlesiretl. or may he roughenetl or punchetl up, as at lll in liigs. 1t and 5. so

portion, Whose outer surface is suitably roughened and broken for the reception of plaster, stucco and thelike, two ofset anges, and two flanges bent back upon themselves to overhang the recessed body portion and extend beyond the side Walls thereof, and an asbestos lining fitted in the recessed body portion and beneath said overhung portions, and retained therein by said overhung portions.
